Diamond is the hardest material on the earth. Polycrystalline Diamond (PCD) tooling is manufactured in a high-temperature and high-pressure laboratory that fuses diamond particles onto a carbide substrate, which allows the diamond to be brazed onto a tool body.

If you’re looking for the ultimate in tooling, you’ve found it! Amana Tool®’s PCD tipped flush trim CNC router bits will trim a wide variety of tough, abrasive materials including composites, particleboard, MDF (both raw or with melamine), veneer and hardwoods. The cutting edge lasts much than carbide for extremely long life.

The ultimate flush trim bit for Aluminum Composite Materials (ACM) and Aluminum. The diamond-tipped cutting edges last much longer than carbide-tipped flush trims, saving you time and money.

*Aluminum Composite Panel (ACP) is a type of ACM flat panel that consists of two thin aluminum sheets bonded to a non-aluminum core. ACPs are frequently used for external cladding or facades of buildings, insulation, and signage. **Durabond is a polyethylene core with 0.3mm colored aluminum sheet on either side, pre-finished requiring no decoration.

Benefits of Diamond Technology

  • Harder cutting edge provides higher resistance to wear
  • Cut thousands of feet more than carbide without changing tool, saving setup time
  • Optimized machine tool efficiency
  • Quality of finish is often significantly improved
